Laptops more susceptible to having keyboard recorded in quieter areas, like coffee shops, libraries, offices. Previous attempts at keylogging VoIP calls achieved 91.7 percent top-5 accuracy over Skype in 2017 and 74.3 percent accuracy in VoIP calls in 2018.
Now I’m wondering if they trained the AI on the exact same machine that they used in their testing. Seems to me that tiny variances in the keyboards of even the exact same model could have significant effects on this sort of thing. And then there’s different levels of wear from usage, crumbs in the keyboard, etc.
I’d be amazed if it is actually this accurate across all machines of the same model.
Yeah it’s more a proof of concept really. The fact it works at different distances shows it doesn’t have to be identical but there’s a lot of factors to take into consideration.
Creating a much larger training set with all sorts of variations would be the next step.
